Particulate matter analysis in indoor environments of urban and rural primary s...
Canha, Nuno; Almeida, S. M.; Freitas, Maria do Carmo; Trancoso, Maria Ascensão; Sousa, Rita; Mouro, Filomena C.; Wolterbeek, H. Th.Passive sampling methodology was applied to collect particulate matter (PM) in classrooms of urban and rural primary schools. The samples were taken during a year by passive deposition allowing the study of seasonal variability of the particles masses and chemical content.Chemical characterization of the collected particleswas performed in order to measure its soluble ions content and elemental composition. To ...
Biomarkers of exposure to metal dust in exhaled breath condensate: methodology ...
Félix, P. M.; Franco, C.; Barreiros, Maria Alexandra; Batista, B.; Bernardes, S.; Garcia, S. M.; Almeida, A. B.; Almeida, S. M.; Wolterbeek, H. Th.In occupational assessments where workers are exposed to metal dust, the liquid condensate of exhaled breath (EBC) may provide unique indication of pulmonary exposure. The main goal of this study was to demonstrate the quality of EBC to biological monitoring of human exposure. A pilot study was performed in a group of metal dust–exposed workers and a group of nonexposed individuals working in offices. Only meta...
Seasonal variation of total particulate matter and children respiratory disease...
Canha, Nuno; Almeida-Silva, Marina; Freitas, Maria do Carmo; Almeida, Susana Marta; Wolterbeek, H. Th.In this work, 14 primary schools of Lisbon city, Portugal, followed a questionnaire of the ISAAC - International Study of Asthma and Allergies in Childhood Program, in 2009/2010. The questionnaire contained questions to identify children with respiratory diseases (wheeze, asthma and rhinitis). Total particulate matter (TPM) was passively collected inside two classrooms of each of 14 primary schools. Two types o...
